Motion sickness in 2d games

[WhaleyStudios]

I am making a 2d platformer and when the character moves I get nauseated.I don’t usually get motion sickness from any game even fps.My theory is that the tiles seem to move when the camera moves.

Well, yes, when the camera is moving, that’s when you’d get motion sickness. How does your camera move? Have you gotten motion sickness from other 2D platformers?

Maybe post a video of the camera movement you’re referring to.

I used cinemachine for my camera and I don’t get motion sickness from other 2d platformers.

Maybe it’s the camera tracking, is it fixed on character or do you have a tracking windows with a dead zone to stabilized it?

Yes the tracking window has a dead zone.

Yes the tracking window has a dead zone.

Please show us your settings and maybe a video or something or we’ll be here all week.

I don’t see anything inherently wrong with what you are doing, but I do have a theory which can be tested. Try replacing your wall texture with something solid and see if you still get nauseous. I feel like the brick texture is what’s causing it. In a repeating block texture like that, it’s possible that in two frames, a block may have moved left on the screen, but because of how it repeats and your framerate, it looks like it moved right.

Say your bricks are 8 pixels wide, this means any movement by more than 4 pixels will actually make it look like the tiles are scrolling backwards, this would certainly make you sick. It’s an illusion called the Wagon Wheel Effect.

My first thought was the texture as well. Looks like a thousand little blocks moving around instead of walls and a floor.

Lock the camera tighter along Y. It shouldn’t drift up and down subtly as you move like that, especially since all you did was jump over a little hill.

Yes, that was the issue all along .Thank you for helping! I will make the brick tiles bigger.

Also the lines between the bricks jump in thickness/brightness, watch the horizontal line at 20-21s of the video turn brighter and thicker. Are you using a pixel perfect camera?
Might not have anything to do with motion sickness though, just seemed distracting to see blinking lines at the corner of your eye when focusing on the character.
